Overview
Divi Scalp Serum is a 30ml, no-rinse leave-in treatment built around a multi-peptide complex, caffeine and rosemary oil. It is marketed for reducing the appearance of thinning hair and calming scalp buildup, and is described as safe for use with hair extensions.
The brand cites its own twelve-week study, in which most participants reported fuller-looking hair and more density, but that figure comes from the brand's marketing copy rather than independent testing. Unlike the acid-based tonics elsewhere in this category, it has no exfoliating acids and is not rinsed out.
